API Reference

LnkApp provides a versioned REST API for all operations. The current version is /v1.

• Base URL: https://api.lnkapp.me/v1
• Authentication: Bearer token (API key)
• Content-Type: application/json

Core concepts

Links

Links are the primary resource. Each link has a slug, destination URL, and optional metadata including tags, UTM parameters, and expiration settings.

Trust scores

Every link has a deterministic trust score from 0.0 to 1.0, computed from destination signals including redirect chains, domain reputation, and availability.

Policies

Policies define rules that govern link access. A policy can restrict access by time, geography, device type, or require authentication.

Organizations

Organizations provide multi-tenant isolation. Each organization has its own members, links, domains, and settings.

Webhooks

LnkApp sends webhooks for link events including creation, updates, deletions, and clicks. Webhooks are signed using HMAC-SHA256 for verification.

• Automatic retry with exponential backoff
• Dead-letter handling for persistent failures
• Configurable event filtering

Rate limits

API requests are rate limited per API key. Current limits:

• Read operations: 1000 requests/minute
• Write operations: 100 requests/minute
• Bulk operations: 10 requests/minute

Rate limit headers are included in all responses.

SDKs and libraries

Official SDKs are not yet available. The REST API can be consumed directly using any HTTP client.
